A partial supernumerary umbilical vein: a case report

Journal of Medical Case Reports, 2019
Background Abnormalities in the number of vessels can be found for both the umbilical artery and vein. We sometimes encounter cases of a decreased number of umbilical cord vessels, such as a single umbilical artery.

Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties

Advanced Science, EarlyView.
Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...

Isolated Single Umbilical Artery and Histomorphometric Changes of Umbilical Blood Vessels in Intrauterine Growth Retarded Foetus in Comparison to Normal Neonates

Journal of Pharmacy and Bioallied Sciences
Background: Three vessels—one vein and two arteries—allow the fetus and placenta to exchange waste, oxygen, and nutrients in the umbilical cord. Single umbilical artery (SUA), a congenital abnormality with one umbilical artery, can occur in some ...

Pseudo-Single Umbilical Artery by Spontaneous Intrauterine Umbilical Artery Thrombosis [PDF]

Perinatology, 2019
Umbilical artery thrombosis is rare event and few prenatally diagnosed cases have been reported. Antenatal diagnosis is very critical, as it is associated with high risk of perinatal motility and morbidity such as intrauterine growth restriction and intrauterine fetal death.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Effects of Hypoplastic Fetal Umbilical Artery on Doppler Findings For Common Iliac Arteries

, 2017
Background: The umbilical cord contains two arteries and one vein. Normally, the diameters of umbilical arteries are close in size, but this may vary, as one umbilical artery may be considerably smaller or more hypoplastic than the ...

Umbilical Artery Thrombosis Masquerading as Single Umbilical Artery in a Stillbirth

Diagnostics
Background: Umbilical artery thrombosis (UAT) masquerading as a single umbilical artery (SUA) is a rare but critical diagnostic challenge in prenatal care. Case Presentation: We described a case of a 22-year-old primigravida with an uneventful obstetric history who presented with reduced fetal movements at 22 weeks of gestation.

Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers

Advanced Science, EarlyView.
Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.

Comparison of umbilical artery Doppler and non-stress test in assessment of fetal well-being in gestational diabetes mellitus: A prospective cohort study

Electronic Physician, 2017
Background: Gestational diabetes mellitus (GDM) is one of the most common medical complications of pregnancy and is related to poor perinatal outcomes. Reduction of neonatal complications of GDM is feasible by assessment of fetal well-being. Both fetal
